If you've ever hit the tab key while typing commands in the shell, you are familiar with the value of shell completions. Bash has some default completion behavior, which is why you can type hel<TAB> and end up with help . It is also possible to add additional completion scripts which define the completion behavior for…
A post describing how C programs get to the main function. Devicetree layouts, linker scripts, minimal C runtimes, GDB and QEMU, basic RISC-V assembly, and other topics are reviewed along the way.
When Apple introduced Bitcode and made it mandatory on watchOS and tvOS, they kinda hand-waved away questions about why it existed, with nebulous claims about it being useful to tune-up binaries by utilizing the latest compiler improvements.
This article is written with considerable snark–put on your flameproof suit if needed. I’m not actually a jerk when interviewing people, but I do get frustrated when candidates fail to do basic preparation. If you’re unsure about how to prepare for a programming interview, read on… I know this might come as a shock to…
I have kept myself busy with the Game Engine Black Books and I have plenty of news. Most importantly, they have been revised. The DOOM book is now in version 1.1 while the WOLF3D book is entering v2.1. And there is more.
We often have to write code using permissive programming languages like C and C++. They tend to generate hard-to-debug problems that can crash your applications. Thankfully, many compilers offer "sanitizers". I discussed them in my post No more leaks with sanitize flags in gcc and clang. I strongly encourage the use…
The idea of a zero cost abstraction is very important to certain programming languages, like Rust and C++, which intend to enable users to write programs with excellent performance profiles with relatively little effort. Since this idea is fundamental to the design of Rust and my work, I want to investigate, for a…
It's not quite the number of seconds since 1 January 1970.
PHP isn't the same old crappy language it was ten years ago
I was at the Microsoft BUILD conference last week and spent some time with a ...
Vim 8.1 was released in May 2018. The “main new feature” was official support for running a terminal within vim. Along with this came a built-in debugger plugin, termdebug, which provid…
Prefer f(void) in C to potentially save a 2B instruction per function call when targeting x86_64 as a micro-optimization. -Wstrict-prototypes can help. Doesn’t matter for C++.
The globalThis proposal introduces a unified mechanism to access the global this in any JavaScript environment. It sounds like a simple thing to polyfill, but it turns out it’s pretty hard to get right. I didn’t even think it was possible until Toon blew my mind with an unexpected, creative solution.
Getting your messages without giving a third party your credentials and data
Update: I've made several edits to the post since Aleksey Shipilëv was kind enough to suggest many corrections and improvements.If you closely follow JVM development scene, you've probably noticed ...
Continuing in the series of posts about lesser-known bash features , here I take you through seven variables that bash makes available that you may not have known about.
A list of free, cross-platform GUI solutions for C++.
There is something very exciting I have to show to you today: a completely rewritten notification system for Plasma that will be part of our next feature update 5.16 to be released in June.
The main reasons Go makes it easier (than Java or Python) to write correct, clear and efficient code are discussed in this comprehensive report by an expert Go and Java developer.
Over the years, I picked up a number of tricks to optimize code. Today I’ll talk about one of them.
Is the traditional 2D imaging model nearing the end of its usefulness, or does it have a shiny future in the “modern graphics” world? I spent a week on a research retreat in a cottage in the woods to answer this question, as it shapes the future of UI toolkits. Performant UI must use GPU effectively, and it’s…
I've been enjoying using Go's database/sql package for working with databases. Recently, some mentions of gorm piqued my curiosity about using ORMs in Go vs. using database/sql directly. Having had some mixed experiences with ORMs in the past, I decided to start with a practical experiment by writing the same simple…
For years now I've had this itch, trying to find the "perfect" collaborative text editor. But not just any collaborative text editor, oh no, my speciality is finding (well, at least looking for) open source real-time collaborative web-based rich text editors...
This is an announcement regarding the resolution of the syntax for the await operator in Rust. This is one of the last major unresolved questions blocking the stabilization of the async/await feature, a feature which will enable many more people to write non-blocking network services in Rust. This post contains…
A common question I get about specs is how to model bad actors. Usually this is one of two contexts: The spec involves several interacting agents sharing a protocol, but some of the nodes are faulty or malicious: they will intentionally try to subvert the system. The spec involves an agent subject to outside forces…
